Specification forming part of Letters Patent No. 129,795, dated July 23,1872 i To all whom it may concern:

.Be it known that I, OWEN DORSEY, of

Newark, county of Licking, State ofOhio,

have invented certain new and useful Improve ments in Side-DeliveryDroppers for Harvesters, of whichthe following is a full, clear,andexact description, reference being had to the accompanying drawingmaking part of this specification, in which- Figure 1 represents aperspective view of so much of a harvesting-machine as is necessary toshow v myfimprovement. Fig. 2 is a longitudinal vertical section throughthe dropping-platform and its supporting-arm, and Fig. 3 is a transversevertical section through the compressor-arm.

Similar letters of reference denote corresponding partsin all thefigures.

My invention relates to that class of droppers or dropper-platforms inwhich the platform is swung upon a vertical pivot from a position behindthe cutting apparatus, where itreceives the grain to one at right angles(or nearly so) thereto, behind the main frame,

moving into position to discharge the grain;

second, in a novel arrangement of means for imparting the swinging orvibrating movements to the tilting-platform; third, in the arrangementof means for tilting the platform;

fourth, in the arrangement of the compressorarm, relative to thecut-off, whereby the latter,

as it is moved intoposition] to receive the falling grain while thegavel is being discharged, is made to operate the compressor and, fifth,in certain details of construction and arrangement hereinafterdescribed.

In the" accompanying drawing, A represents the main frame of themachine, which may be of any usual construction and mounted on one ortwo driving-wheels,B,'as preferred. 0 is the finger-bar, connected withthe rear end of the frame'A, and provided at its outer end with theusual divider D and grain-wheel D. E is a shoe, whichis connected to thefinger-bar at its inner end, and, extending in rear of said bar, affordsa support for the vertical platform-shaft or pivot-block F. Thispivot-block is, by'preference, cast in one piece with the horizontalparallel supporting-arms F F, upon the outer swinging ends of which thedumping-platform G is mounted; but it may be made of any suitablematerial, either wood or metal, with the arms applied to it by mortiseor tenon, bolting, or other convenient manner, and it maybe made in onepiece with the pivots f f, or the pivots may be applied as shown insectional view, Fig. 2. The blockF .isprovided with lugs or cars f towhich the pitman is connected for operating the block and platform, ashereinafter described. The platform G,forfpurposes of lightness andstrength, is, by preference, composed of light longitudinal slats g,which, when the platform is in position to receive the grain, lieparallel with the finger-bar, and which are united to transverse bars g9 arranged I underneath bars 9, so as to leave the upper plane surfaceof the slats unobstructed for the delivery of the grain when tilted, thebars g 9 being arranged, one, g at the inner end of the slats g, and theother, 9 near midway of the length of said slats. To the bars 9 gisattached a latch arm or bar, H, which extends inward beyond bar 9 atthe inner end of the plat- 1 form, for looking or holding the 'platformin its horizontal position for receiving and conveying the, grain to itspoint of discharge, as will be explained. 11 is aspring-latch, pivotedto the platform-block F, and held in proper position for locking thelatch-arm H by means of a spring, h. The latch-arm His also made in thepresent instance to serve as thepoint of the pivotal connection betweenthe platform and the arms F," as shown at i,

Fig. 2; but it will be obvious that these may be separate, and that thelatch-arm may be connected to the inner end "of the platform only. I isa spring attached to the shoe E, or to the pivot-block or arms FF, fortilting'the platform when released from the latch H '1' J is an angularor bell-crank lever, pivoted'to the pivot-blockF, so as to move withit,with its lower horizontal arm extending outward by the side of theplatform-supporting arm F, and passing'through a loop or eye or over aplate, j, attached to the platform, theouter end of said arm being bentor hooked at 7" to limit the tilting movement of the platform. Thevertical arm or lever J moves in contact with, and is operated by, aninclined or curved way or track, It, formed upon an overhanging plate,K, and so arranged that as the tiltingplatform, after having dischargedthe gavel, is swung from the position shown in the drawing into aposition to receive another gave], the wayor track It acts upon thevertical arm of lever J, and, depressing the outer end of the horizontalarm, serves to restore the platform through the connection with said armto a horizontal position for receiving the grain, and in which positionit is locked and held by the latch H as above explained. The arm K, withits cam-way k, is made adjustable to regulate the movements and throw ofthe tilting-platform by a slot and set-screw at k, or other suitabledevice for that purpose, and the latch H is operated, for releasing thetilting-platform at the desired point for discharging the gavel, bymeans of an adjustable stop, H which comes in contact with the upper endof said latch H in a manner that will be readily understood withoutfurther explanation. L is a horizontal compressor-rod mounted in an arm,L attached to a rock-shaft or head, L which is pivoted in bearings inthe inner transverse platform-bar g and a supplemental bar or block, gThe head or shaft U is squared in one portion of its length, (shown insection, Fig. 3,) and has resting upon its lower face a flat spring, I,attached to bar 9 which acts upon the square or flat face, and tends toprevent rotation of the shaft and to lock it in the position in which itmay be set. L is an elastic rod or spring attached to the upper end ofarm U for depressing said arm, as will be hereinafter described. M is anarmrod or stop attached to the rear end of the frame in position tostrike and act upon a spur, l, on the shaft L as the platform swingsinto position to discharge the gavel, in such manner as to overcome thetension of spring I and allow the shaft L to be rotated to raise thecompressing-rod L ofl the grain on the platform to the position shown inthe drawing, where it remains until the platform has received anothergavel and commences its move ment toward the place of discharge, when itis again thrown down to hold the gavel and prevent scattering of thegrain, as will be described. N is a post or upright, mounted either onthe main frame, finger-bar, or inner shoe, as may be preferred; and tothe upper end of this post a cut-oif arm, 0, is pivoted by its upperend, the lower end being provided with a socket to receive the swingingcut-off or horizontal rod or bar 0, which is interposed to receive andsupport the falling grain while the platform is discharging its load. Pis a pitman, connected at one end to the ears f of the verticalrake-pivot or block F, and at its other to the swinging end of an arm,Q, attached at its opposite end to a vertical rockshaft, R, mounted inbearings in the main frame in advance of the drivers seat S. P is I asecond pitman, connecting the cut-off arm 0 with the pitman P in suchmanner that by the movement of the pitman P, which operates the swingingplatform, the cut-off is operated simultaneously with the platform. R isa rocking treadle-lever attached to the upper end of rock-shaft R, andarranged in convenient position to form asupport for and to be operatedby the drivers feet.

The operation of the parts above described will be readily understood.Supposing the parts to be in position represented in Fig. 1, the driverby pressing with his right foot up on the rocking-lever R vibrates theshaft R, and with it the arm Q, giving to the pitmen P P a backwardthrust, which, in consequence of the arrangement of the point ofconnection of pitman P with the inner side of pivot-block F, serves toswing the platform inward and forward toward the fin ger-bar intoposition to receive the falling grain. While this is being done theelbow-lever J is operated by the camway k, as described, to restore thetilting platform to its horizontal position, in which it is locked bylatch H and simultaneously therewith the cut-off O is swung backward andupward out of the way, allowing the grain accumulated thereon to dropupon platform G, the elastic arm or spring L yielding and passingunderneath the cut-off 0, when it springs upward and assumes a positionimmediately in front of cut-ofi' 0, where it remains until the gavel iscompleted. When this is done the movement of lever B is reversed,

and the dropper O in descending comes in contact with arm L causing thearm L to be thrown down until rod L rests upon and compresses the grainupon the platform, and prevents it from being scattered during theswinging movement of said platform. The

cut-0E O descends into position to receive the falling grain, and theswinging movement of the platform is continued until the spur l strikesthe stop-arm M, raising the compressor-rod L and releasing the grain,while simultaneously therewith the latch 11, coming in contact with stop11, releases the platformarm H, and allows the platform to be tilted byspring I, as above explained. I When the platform is swung into positionto receive the grain the outer ends of the slats composing the same passunderneath the rear extended end of the divider-board D, which overhangssaid slats and prevents waste of grain at that point. The platform andcut-off, instead of being operated by the driver, may, if preferred, beconnected with and automatically operated by the gearing of the machinein any convenient manner.

Having now described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. The combination of the holding or compressing-rod with the swingingdropper-plat form, substantially as and for the purpose described.

2. The compressor-rod L, operating, in com bination with the"dropping-platform, substantially as described, in combination with thecut-off for depressing, and the stop M or equivalent device for raising,said rod, as set forth.

3. The swinging and dumping platform and vibrating cut-off, incombination with the pitmen P P and treadle-lever R, arranged andoperated substantially as described.

4. The swinging anddumping platform G,

provided with the latch-arm H, in combination with the pivoted latch 11for holding and releasing the platform, as described.

5. The combination, with the swinging and dumping platform, of thespring I, for tilting the platform when released from its holding orlooking device,,as described.

6. The elbow-lever J and inclined or curved cam-way or track k, foroperating the tiltingplatform and returning it to its horizontal 7position for receiving the grain, as described.

7. The stop H which operates the latch H for releasing the platform,made adjustablefas described, for the purpose of regulating the point ofdischarge of the gavel, as

set forth.
